Populations are growing, especially in Africa and Asia. The number of people dying from pregnancy and childbirth is decreasing, and the average life expectancy has increased by nearly 10 years since 1990.
However, no matter how many people there are, the size of the earth will not change, and resources will not increase. Resources will not increase either. In other words, as the number of people increases, the earth's environment will be affected. Naturally, we will run out of oil and other energy sources. And food shortages are expected to become even more serious.
Thus, population growth poses a very serious problem. It is time for us, who will continue to live on this earth in the future, to seriously consider and solve this problem.
